SFFS: More From "Downtrodden"

Well, back in the saddle again this week. Last time we saw Aston in "Downtrodden" he was getting interrupted while stopping a pickpocket. Poor Aston never can catch a break, as anyone who's followed my snippets on Science Fiction Fantasy Saturday can confirm. We continue on this week with "Downtrodden" and as always, if you like this snippet (hopefully you've read the previous snippets), be sure to check out my current released Triple-Shots, shown below. Three short stories in each edition, all featuring space pirate Aston West in his various adventures.

And now, for the snippet (and the repeated disclaimer that this is mostly first-draft material):

I looked up, fury filling my heart at the woman interrupting my lesson in negative reinforcement. Then, I did a double-take at the pale-faced redhead just before she smacked me across the face. I released my grip on the boy, whom she snatched up from the ground. I couldn’t tell whether he’d successfully pilfered my funds, but wasn’t about to let this pair get away with it if he had.

Yanking my blaster out, I flipped the switch next to the trigger. “That’s fully automatic, in case you were curious.”

“Put that thing away!”

“I plan on searching that kid for my money.” I aimed the barrel at her face more for emphasis than anything. “So, if you’d care to hand him over...”

Aston taking the initiative? Well, now I've seen everything! While you're waiting for next week's snippet, be sure to go check out the rest of the Science Fiction Fantasy Saturday snippets and don't forget to buy some books. You'll be glad you did.

Do Free Giveaways Impact Sales?

As many of you (hopefully) know, my e-book Seeker has been available for free since the last part of May on most sites. One of the benefits I've hoped for out of this experiment is to see a jump in sales of my for-pay titles. I will mention that as of the end of July, 591 copies had been given away on Amazon.

So, I'll take a look at some of the titles for which I receive instantaneous sales data (i.e., my self-published titles)...starting with my Triple-Shots, which are available for 99 cents each.

So, before Seeker was free, for the first 5 months of the year, these titles sold a combined 2 copies at Amazon. Fairly dismal, especially since they're relatively cheap to pick up. Perhaps people see the low price and assume that they're poor quality...that's another post for another time. But after Seeker was set to free, for the last two months or so, they've combined for a total of 17 sales at Amazon, a major jump in sales over a much shorter period of time. My impression is that folks read the free title, realize that I actually have the ability to spin a fine story, and then pick up the 99-cent titles.

The Cure, on the other hand, didn't seem to enjoy the same benefit. No copies sold the first five months of this year, and only 1 copy sold since. That's understandable, since Seeker is an Aston West novel, and The Cure isn't (even though it does come into play in my next planned Aston novel.

Death Brings Victory, another Aston-based novel, hadn't sold a copy in the first five months at Amazon, but has sold 6 copies since then. A huge jump, to be sure, but not as significant as the Triple-Shots mentioned earlier. Part of this is likely due to the larger price ($2.99 vs. $0.99), but another aspect is likely the fact that this is the third in the series, and readers likely want to try out the first two novels before this one.

Just off Author Central data, I did see an uptick in sales on those first two novels, but quantities won't be known for some time (waiting on royalty statements).

So, do free giveaways impact sales? Just from this data, I'd give a resounding yes...and if you're looking to help out your own sales, give it a try. One thing I will note is that the last two months have been a continuous streak of free giveaway days. I had a book enrolled in the KDP Select program previously, and the 5 days every 90 did not seem to have the same effect. Keep that in mind...

Amazon Rankings: A Statistical Analysis?

Apologies for missing out on this week's SFFS posting...the week's been a mess with many things going on, and by the time I gathered myself together, I'd already missed the deadline for signing up. Hopefully, next week, we'll get back into my short story "Downtrodden" but for now, I wanted to post some information on a favorite topic of mine.

Those pesky Amazon sales rankings...everyone wonders how they come up with the numbers they do, and how they correspond to sales (especially for books where you haven't self-published through the KDP program, and you don't have instant access to your sales numbers, although things are a little bit better now that you can review historical data on sales rankings of all your books through Author Central).

Everyone (hopefully) knows the basics of sales rankings. The lower the number, the more copies you've sold. If a copy of your book sells, the number gets lower. As time passes without sales, your number gets higher. But how exactly do they determine the number? I've taken some sales numbers for my two Triple-Shot collections for about a month's period, and am going to run some analysis on those. The reason is simple. My books don't sell hundreds of copies a day (in fact, each of these changes takes place after a single copy of each sold), so it will hopefully give some insight into how sales impact the ranking.

Just for having all the facts, I'll mention at the time of this posting (and at the time of these sales listed below), DMF had two 5-star reviews, and Temptation had one 4-star review. Also, DMF has more total sales, but Temptation has sold 50% more copies this year than DMF.

So, let's first look at my first Triple-Shot, featuring "Dead Man's Forge." Each date range corresponds to the three-day period surrounding the date of purchase, and the rankings on each day.

18-Jun 19-Jun 20-Jun
621463 83959 158286
21-Jun 22-Jun 23-Jun
242962 116176 204661
24-Jun 25-Jun 26-Jun
270981 79911 185757
30-Jun 1-Jul 2-Jul
383636 91069 155854
5-Jul 6-Jul 7-Jul
346592 87791 166719
14-Jul 15-Jul 16-Jul
464262 82844 127117

And now the numbers for the second Triple-Shot, featuring "Temptation" (note: the first has four dates, as two copies sold, once on the 15th and another on the 16th)

14-Jun 15-Jun 16-Jun 17-Jun
1101143 100249 72888 159123
18-Jun 19-Jun 20-Jun
225398 79764 150470
21-Jun 22-Jun 23-Jun
227376 114281 200625
30-Jun 1-Jul 2-Jul
454136 91333 156508
6-Jul 7-Jul 8-Jul
389278 90126 205350
14-Jul 15-Jul 16-Jul
464331 82883 127182

And now for the analysis...

First off, notice that Temptation sold two copies on sequential days (the first line of the data), but yet the ranking on that second purchase didn't boost it much higher than the other times that a copy was purchased.

Notice also on those date ranges where copies of both books were sold, that the increase in sales rankings were not a matched amount, and that on the following days, the drop in sales rankings were not linear between the two (i.e., one book dropped faster than the other).

Also notice that on two separate sets of days, the starting ranking for Temptation was almost identical (6/18 and 6/21), but a single copy caused it to boost to different rankings after the sale.

Now I will mention at this point that Author Central gives you a daily ranking, but doesn't tell you when the book sold during the day. I've sat and studied it by anecdotal means, but there's no way to record such data that I know of. A copy sells and boosts the ranking, and immediately begins dropping, but the AC value usually matches up to a value somewhere along the path down.

So, what are we to make of all this? I have a theory I'd like to share:

I believe until you start selling multiple copies per day, that you're included in a vast range of numbers starting at some value determined by repeat daily sales-books (likely in the 70K range). When your book sells a copy, you're bumped up to the top of that list. The next single-sale book that sells out of the Kindle store moves you down the list (unless a book starts selling more than one copy per day, in which case it gets bumped to the next tier up), and each subsequent book moves you farther down the list. Author Central would then take a snapshot at the end of each day, which is the number that gets published to your ranking chart. The only thing I'm not sure about is whether reviews get added into the equation somehow...I have an additional theory that if books are sold at around the same time (perhaps in a 5-minute window), that the number and level of star-ratings boost a book higher than the other with fewer and/or lower ratings. I'm also not sure how a book that was selling multiples per day affects the rankings when it stops selling that many on a particular day, but my belief would be that it drops back down into that lower tier and pushes copies that had just sold a copy that day down.

This would explain how a book that was sitting at nearly one million in the rankings (as mine was) would immediately reach a value of about 100K, but then sell a copy the next day and only bump up to about 73K. 

This would also explain how books that sell on the same day ended up moving up to different rankings, because if they sold later in the day, their ranking would by default be higher than another book that sold earlier in the day.

This would also explain how a book drops faster than another, if a book drops down to the lower tier before another book sells a copy.

Obviously this is just conjecture on my part, so maybe one of you out there has a theory they'd like to share, or another comment to make of some sort. Suffice to say, that Amazon truly does have the market cornered on keeping around the most complex algorithm for sales rankings known to man.

Please, feel free to comment and discuss...
